Commercial sealant in Shacklewell

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Mr Mastic brings more than 20 years’ experience to commercial sites, and we are fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can supply with the quote. If you’re dealing with whole floors of tired en suites and tired sealant in let properties, we can help.

In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Shacklewell, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Commercial sealant around Shacklewell

There are hotels and other places to stay in and around Shacklewell. Hotel work can be planned room by room, with out-of-hours working where needed. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

If you look after a building such as The Petchey Academy, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. As a London address, Shacklewell can be tricky for parking: let us know about parking bays, permits or a driveway.

Do you need commercial sealant in Shacklewell?

Internal washrooms and en suites without a window rely entirely on extraction, so if the fan is weak, steam lingers and the sealant stays damp. That’s when black mould sets into the bead.

Common reasons people contact us include:

  • Split sealant where wet room floors meet walls
  • Black, stained silicone in guest bathrooms
  • Washrooms that need sorting before an inspection
  • Silicone laid over old silicone by a previous contractor

If you let a flat or house near Rectory Road station, several rental properties can be resealed on one programme.

How to choose a mastic man

How it works

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a morning for a small washroom, and a planned programme for bigger sites. In a London area like Shacklewell, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. We agree when we will work, with early or out-of-hours slots where they can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height
  • Clear items away from the joints we’re working on

Why deal with it now?

Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Shacklewell.

A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What you get with us

  • Old sealant always removed completely
  • ARBOMaster approved applicator
  • Over 20 years’ experience
  • Fully insured

Questions from Shacklewell

Can parking be tricky for a visit in Shacklewell?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

I let a flat near Rectory Road station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can you work outside opening hours?

Out-of-hours work and early starts can be arranged. Tell us what you need when you ask for a quote.

Do you cover Shacklewell?

Yes. We cover Shacklewell. For a quote, call 0345 464 0079 or drop us an email.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do you take on large, multi-room jobs?

Yes. With more than 20 years’ experience and over 2,847 projects behind us, we plan big jobs so the building keeps running.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.

What affects the cost of commercial sealant

Jobs vary more than people expect. What affects the quote:

  • The amount of work
  • When we can work, for business premises
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • The type of property
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any access issues, like height or stairs

If you are in Shacklewell and need commercial sealant, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we’ll agree the price before any work begins.
